TO ALL WHOM THIS MAY CONCERN:

30 it known that I, SILAS GREXELL, of Mokena, in the county of Will, and State of Illinois, have invented a new and useful Improvement in Seed-Sewer; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation, reference being bad to the accompanying drawings, and letters of reference marked thereon, making a. part of this description, in which- Figuri-v 1 is a perspective representation of my seed-sower.

Figure In. Section of the same. I

he nature of my invention. consists in the use of a series of cups having arms attached to a shaft, which is made to revolve in a circular trough and cause seed gathered by the cups to be thrown on to a curved spreading-himrd, from-which it may fall on the ground evenly, or what is known as broadcast. I

in order to give a correct understumling of my device, I have marked each part in the drawings with corresponding letters, and will now give a detailed description. I

A-shows the'n'heels, B thcaxle, and C the shaft which-supports my seed-sewer, and is a very common construction of its kind. D represents a circulartrough, having the ends E and vertical partition F placed over the shaft C. This trough D is held in position by arms G, fitting into loops H, secured rigidly to ends E, and also by bearing upon shaft C. I is the shaft which operates the cups J, and is supported by ends E, fig. and driven by belt K passing over pulley L, attached to shaft I, and pulley M, attached to wheel A, in the usual manner. I use any desired number of cups J necessary to throw a suitable quantity of grain upon. the spreading-board O O, and attach them to shaft I by means of curved arms S, and arrange them to operate closely to the bottom of trough D, so as not to leave much grain in it after the cups J cease to fill. The sp1-ezuling -bea1'd is made in two parts, so as not to interfere with shaft C, and the outer ends are made fast to the parts E, and held near the shaft C by means of strnp- U, fig. 2. R shows a. fly-board attached to trough D, and extending the entire length of spreading-board O O, and used for preventing dirt and wind from distnrbing the seed as it is passing to the ground. The upper edge of board 0 O is made to project above the inner edge of trough D, for the purpose. of preventing the cups J from throwing the grain over to the back of the sewer. I? is a hopper, which supplies the trough D by means of holes Z, figs. 1 and 2, made in the back of trough D,vnear the lower angle of said hopper. I

By this general arrangement a very convenient, cheap, and suitable seed-sewer is provided, and having but little gearing, and not liable to get out of order.

Operation.

The sowcr can be detached from axle B byi'taking out bolts Y from the ends of arms Gr and loosening band K. By this arrangement it will be seen that the device can be attached to any ordinary axle and wheels, having a drum, M, for operating belt K. The seed should be put in hopper P in the usual manner, after which it will be properly sown without further care, when the wheels are caused to move forward at the usual rate of speed. 7

Having thus fully described my seed-sewer, what I claim, and desire to secure by Letters Patent, is- The combination of trough D, spreading-board O O, shaft I, having arms S and cups J, and hopper P, when arranged to operate substantially as described.

2. The ends E having the loops H, in combination with the arms G and rod I, as described and for the purpose set forth.
